Calling all Jackie and Kelso fans! Mila Kunis and Ashton Kutcher could be engaged.

According to E! News, a source says the two are indeed planning to marry, especially after Kunis was reportedly spotted with a diamond ring Thursday (Feb. 27).

This will mark the second wedding for leading man Kutcher, who was previously wed to actress Demi Moore, before they called it quits in September 2011.

The former 70's Show stars were first spotted as a couple back in April 2012, though it took months to make their status as an item official.

Should the whispers be true, only question remains is: Dude, when's the wedding?
